Pantry staples meet deli counter finds for this cozy slow cooker meal.
| Ingredient | Amount | Notes |
|---|---|---|
| Italian Sausage 🌭 | 1 lb | Casings removed, mild or spicy |
| Ground Beef 🥩 | ½ lb | 80/20 lean-to-fat ratio |
| Yellow Onion 🧅 | 1 whole | Diced, about 1 cup |
| Garlic Cloves 🧄 | 4 cloves | Minced for depth of flavor |
| Crushed Tomatoes 🍅 | 2 cans | 28 oz each, San Marzano preferred |
| Tomato Paste 🍅 | 2 tbsp | For concentrated tomato flavor |
| Beef Broth 🥣 | 4 cups | Low-sodium for balance |
| Dried Basil 🌿 | 1 tsp | Or 1 tbsp fresh basil |
| Dried Oregano 🍃 | 1 tsp | Mediterranean variety preferred |
| Lasagna Noodles 🍝 | 8 oz | Broken into bite-sized pieces |
| Ricotta Cheese 🧀 | 1 cup | Whole-milk for creaminess |
| Mozzarella Cheese 🧀 | 2 cups | Shredded, low-moisture |

The sausage sets the tone here. Johnsonville mild Italian is my go-to (sold at most supermarkets), but any good brand works—just avoid pre-cooked links. The San Marzano tomatoes are worth hunting down at Whole Foods or a specialty store for that sweet, rich base. If you can’t find them, any crushed tomatoes will do, but drain some liquid so the soup isn’t watery.
No Italian sausage? Ground turkey or pork with a pinch of fennel seeds gets you close. Swap beef broth for chicken or vegetable broth if that’s what you’ve got. The ricotta can be cottage cheese in a pinch (blend it smooth first). Skip the spinach if you’re not a fan—fresh basil at the end adds a nice pop of color and flavor instead.
This keeps well—actually tastes better after 24 hours as flavors meld. Store in the fridge for up to 4 days or freeze for 3 months. Reheat on the stove with a splash of broth to loosen it up.

Step-by-Step Instructions for Lasagna Soup Slow Cooker
This hands-off method delivers all the comfort of lasagna without the layering fuss.
Step 1: Brown the Meats and Aromatics
Heat the 1 tbsp Olive Oil in a large skillet over medium-high heat. Add the 1 lb Italian Sausage (casings removed) and 0.5 lb Ground Beef, breaking them up with a wooden spoon. Cook for 6-8 minutes until browned and crumbly.
Add the diced 1 whole Yellow Onion and minced 4 cloves Garlic Cloves to the skillet. Continue cooking for 3-4 minutes until the onion softens and becomes translucent. This builds a deep flavor base for your soup.
Step 2: Build the Soup Base in the Slow Cooker
Transfer the browned meat mixture to your slow cooker. Stir in the 2 cans Crushed Tomatoes, 2 tbsp Tomato Paste, and 4 cups Beef Broth. These liquids create the rich, tomato-forward broth that defines this dish.
Add the 1 tsp Dried Basil and 1 tsp Dried Oregano, stirring to combine. Set the slow cooker to low heat and cook for 4-5 hours, allowing the flavors to meld and deepen. The aroma will fill your kitchen with that classic lasagna scent.
Step 3: Add Noodles and Finish Cooking
Stir in the 8 oz Lasagna Noodles (broken into bite-sized pieces) during the last 30-45 minutes of cooking. This timing ensures they become tender but don’t turn mushy. The noodles will absorb some of the broth, thickening the soup slightly.
You’ll know they’re done when they’re al dente—firm to the bite but fully cooked. If the soup seems too thick, add a splash of water or additional beef broth to reach your desired consistency.
Step 4: Stir in Greens and Cheese
Just before serving, stir in the 2 cups Fresh Spinach. It will wilt in 1-2 minutes from the heat of the soup. This adds a fresh, vibrant element to balance the richness of the dish.
Ladle the soup into bowls and top each serving with a dollop of 1 cup Ricotta Cheese, a sprinkle of 2 cups Mozzarella Cheese, and a dusting of 0.5 cup Parmesan Cheese. The cheeses will melt slightly from the heat, creating that signature lasagna experience.
Pro Tips For Making Lasagna Soup Recipe Slow Cooker
- Brown the Meat First: I learned this the hard way—skip the slow cooker for the sausage and beef initially. Sear them in a pan first to lock in flavor, then transfer everything to the slow cooker.
- Crush the Tomatoes More: After burning three batches, I finally figured out that crushing the tomatoes by hand or blending them briefly makes the soup thicker and heartier.
- Don’t Overcook the Noodles: Add uncooked lasagna noodles only in the last 30 minutes, or they’ll turn mushy. Yes, even if you’re impatient like me.
- Use Fresh Garlic: My grandmother swore by this, and she was right: fresh minced garlic tastes noticeably better than the jarred stuff in this soup.
Troubleshooting This Dish
Noodles Too Soft
If your noodles turn mushy, you likely added them too early. Stir in the 8 oz Lasagna Noodles only during the last 30-45 minutes of cooking. For extra control, cook them separately and add to bowls when serving. I learned this the hard way after a few over-soft batches. 💡
Thin or Watery Soup
This often happens with excess liquid from tomatoes. Use San Marzano crushed tomatoes and drain some liquid before adding. If already thin, remove the lid and cook on high heat for 30 minutes to evaporate excess moisture.
Bland Flavor Profile
Boost the taste by adding 1 tsp salt and ½ tsp black pepper to start. Don’t forget the 2 tbsp Tomato Paste—it’s crucial for depth. If still lacking, stir in 1 tsp Italian seasoning or a pinch of red pepper flakes.
Cheese Not Melting
Use whole-milk ricotta and low-moisture mozzarella for best results. If your cheese sits in clumps, ladle hot soup over it in bowls and let sit for 2-3 minutes. Freshly grated Parmesan always melts beautifully.
Greasy Surface Layer
Skimming fat is key. After browning the 1 lb Italian Sausage and 0.5 lb Ground Beef, drain excess grease before adding to the slow cooker. If you see a greasy layer after cooking, skim it off with a spoon before serving.
Spinach Overcooked
Add the 2 cups Fresh Spinach right before serving. It only needs 1-2 minutes to wilt. For even better texture, place raw spinach in bowls and ladle hot soup over it. This keeps it vibrant and tender-crisp.
Frequently Asked Questions
Can I use regular lasagna noodles?
Yes! Break them into 2-inch pieces before adding. They’ll soften perfectly during the last 30-45 minutes of cooking. No need for special noodles.
Why brown the meat first?
Browning develops deep flavor and renders fat you can skim off. It adds a rich, caramelized base that makes the soup taste far more complex.
Can I make this vegetarian?
Swap meat for 1 cup lentils and 1 cup mushrooms. Use vegetable broth and add extra 1 tsp Italian seasoning for depth.
How do I store leftovers?
Cool completely, then refrigerate in an airtight container for up to 4 days. Freeze for 3 months if needed. Reheat gently with extra broth.
